GAS-FURNACE Specification of Letters Patent.

fatented. June 2, 1908.

Application filed. February 25, 1907. Serial No. 359,212.

To all whom it may concern:

Be it known that I, EMRY A. NEwooMB, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Gas-Furnaces, of which the following is a specification.

My invention relates to improvements in gas furnaces.

The object of my invention is to provide a gas furnace so constructed asto effect perfect combustion combined with large relative heating capacity.

The object of my invention is to provide also mechanism by which an ordinary hot air coal furnace may be readily converted into a gas burning furnace.

My invention provides further, a combustion chamber for burning the gas, comprising telescoping and upper and lower parts,where by the combustion chamber may be adapted to furnaces having the-fire pots disposed at different distances from the base of the furnace.

My invention provides further, means by which the combustion chamber may be fitted to the inner periphery of the fire pot.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate my invention'Figure 1 is a central, vertical section of a furnace provided with my invention. Fig. 2 is a vertical sectional view, taken on the dotted line e-f of Fig. 1. Fig. 3 is a horizontal sectional view taken on the dotted line gh of Fig. 2, the dome supported by the fire pot being removed. Fig. 4 is a horizontal sectional view, taken on the dotted line i-y' of Fig. 2. Fig. 5 is a horizontal sectional view taken on the dotted line kl of Fig. 1.

1 denotes the furnace casing and 2 the fire pot ordinarily mounted therein and supported by any suitable means, not shown. Upon the upper end of the fire V ot 2 is mounted what I term a distributor, aving a central, downwardly extending conical portion 3 and provided with an upwardly converging perforate portion, comprising preferably a horizontal ring 4, supporting a smaller ring 5, which in turn supports the conical plate 3, the ring 5 having one or more vertical holes 6 disposed in a circle around the conicalgplate 3.

7 denotes a concavo-conveX dome, encircling and su ported by the fire pot 2 and provided wit the usual horizontal smoke pipe 8, which extends through the casing 1.

The rings 4 and 5, for convenience in inserting within the casing 1, preferably comprise two halves.

The air to be heated is admitted by suitable openings, not shown, in the bottom of the casing 1, and passes between the casing and the fire-pot 2, and is discharged through the usual outlets in the upper end of the casing into the hot air tubes, not shown.

9 denotes the fire bowl, preferably cylin drical, and having a closed lower and anopen upper end, and provided preferably on its lower end with legs 10, which rest upon the base 11 of the furnace. A vertically adjustable tubular jacket has its upper and lower ends fitted respectively to the fire pot 2 and bowl 9. Said acket comprises preferably, a plurality of concentric, vertical rmgs or tubes 12, 13 and 14, the outer ring 14 being fitted to the inner periphery of the fire pot 2, and resting upon the peripheral lugs 15 of the fire pot 2. The upper end of the ring 13 is provided with a horizontal annular flange 16 which rests upon the ring 14. A ,similar annular peripheral flange 17 is provided on the upper end of the ring 12 and is supported upon the ring 13. An inverted bowl-shaped baffle device comprising, preferably, two semicircular plates 19, has its lower end mounted upon the ring 12 and is provided with a central vertical discharge opening 20 encircled by a vertical upwardly converging tube 21, which discharges the burning gas against the conical projection 3. An annular asbestos lining 18 is preferably inserted between the rings 12 and 13, for retaining the heat within the combustion chamber which comprises the bowl 9, ring 12 and baffle plates 19. The bowl 9 is provided on its inner side with an annular cast iron lining 22 provided on its forward side with a cut out portion 23. Preferably interposed between the cast iron lining 22 and fire bowl 9 is an asbestos lining 24. The rings 12, 13 and 14 are preferably each formed in two equal halves for permitting the insertion of said'rings into the casing, 1. Within the annular lining 22 in the fire bowl 9 is a deflector comprising an upward and rearward inclined plate 25, having on its upper side one or more vertical partitions 26, which form compartments into which the gas and air is discharged.

Outside of the casing 1 is provided a horizontal header tube 27, one end of which is closed by a plug 28, the other end having connected to it a conductor 29 connected with any source of gas supply. The header 27 is provided with one or more lateral outlets in which are mounted one or more gas discharge tubes 30, said gas discharge tubes being controlled respectively by the ordinary gas cocks 31. Disposed in a horizontal row are one or more horizontal tubes 32, each provided with one or more longitudinal slots 33 and each tube 32 having one open and one closed end, the closed end being provided with a gas inlet opening in which is mounted the adjacent gas tube 30. One or more horizontal mixing tubes 34, which extend through openings provided in the casing 1, and bowl 9 and discharge respectively into the com Eartments upon the upper side of the deector plate 25, are longitudinally adjustable respectively in the tubes 32. The said tubes 34 are preferably slidably mounted in the tubes 32 and are rigidly held in the position in which they are adjusted by means of set screws 35, which extend through the slots 33 and engage threaded openings provided respectively in the tubes 34. A horizontal row of air tubes 36 extend through the bowl 9 and casing 1, and through openings provided in lugs 37, on the under side of the header tube 27. To secure the tubes 36 to the header tube, the lugs 37 are provided with threaded openings in which are mounted set screws 38 which bear against the air tubes 36.

The header tube 27 is provided with a gas cook 3'9, having a tip .40 at which gas may be burned.

The air tubes 36 are disposed preferably one below each mixing tube 34, so that each compartment on the deflector plate 25 will be supplied with a plentiful amount of fresh air. y providing the separate compartments on the deflector plate 25, smothering of the burning gas is prevented, the inclination of the late 25 and the air jets coming from the tubes 36 causes the burning gas to be rapidly carried upward and taking with it sufficient air for perfect combustion. The conductor 29 may be provided with a valve 41 which controls the passage through the conductor of the gas.

The parts having been assembled as described, the cook 41 is turned so as to admit gas into the header 27 and the cocks 31 are turned to permit gas to pass from the header into the tubes 30, through which the gas is discharged into the tubes 32. The gas passes from the tubes 32, together with air entering the tubes 32 through the slots 33, into the tubes 34 and thence into the compartments upon the upper side of the inthe furnace fire clined deflector 25; The gas is ignited after issuing from the tubes 34 and mixing with air entering the bowl 9 through the tubes 36, passes upward through the tube 21 and strikes the conical deflector 3 by which the burning gas is spread laterally in the fire pot 2, after which it passes therefrom through the holes 6 into the dome 7, thence passing outward by way of the smoke pipe 8.

Various modifications of my invention may be made within the scope of the appended claims, without departing from its spirit.
